FRANK S. INGOLDSBY, OF ST. LOUIS, MISSOURI, ASSIGNOR TO THE INGOLDSBY AUTO- MATIC CAR COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF WEST VIRGINIA.

OAR.

T 0 all whom it may concern:

Be it known that I, FRANK S. INGoLDsBY, a citizen of the United States, residing at St. Louis, State of Missouri, have invented a certain new and useful Improvement in Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

One of the objects of this invention is to provide a very efiicient floor frame for cars.

The invention is well adapted for level floor dump cars, and especially such cars of the Ingoldsby type, wherein there is a central longitudinal supporting structure to which are hinged the doors, which extend outwardly to the car sides.

The present invention is concerned particularly with the longitudinal center member, which in the preferred form is composed of a pair of rolled shapes surmounted by an inverted U -shaped structure held thereto on bridges arranged at points corresponding to the struts and ties of a truss. By this means I am enabled to obtain at once a very stiff and light member. The member is also very strong, the parts be ing arranged with reference to the strain which comes upon them so that the various rivets are in shear.

My invention, furthermore, provides cross shaped members forming a portion of both the longitudinal member and the cross members to the car sides; these cross-shaped members having their longitudinal arms in compression, and their cross arms with extensions thereof, acting as lateral braces and load supporting beams between the center member and the sides.

The top of the longitudinal member, as well as of the cross members, being rounded, they provide shedding surfaces discharging into openings between them, when the doors, which normally occupy such openings, are dropped.

The invention is hereinafter more fully explained and is illustrated in the accompanying drawings.

In the drawings Figure 1 is a plan of a level bottom dump car embodying my invention. Fig. 2 is a side elevation on an enlarged scale of a portion of the longitu Specification of Letters Patent.

dinal center member, being a vertical section on the line 22 of Fig. 1. Figs. 3 and 4 are cross sections, as indicated by the correspondingly numbered lines in Fig. 1. Fig. 5 is a sectional plan of the longitudinal center member, the section being taken a short distance below the crown. Fig. 6 is a perspective View of the shedding cross at the junctions of the longitudinal and cross members, showing also the channel beneath the cross arms. Fig. 7 is a detail in cross section illustrating a modified means for carrying the hinge pintle for the dumping doors.

Referring to the parts by reference numerals, 10 represents the sides of the car, which may be plate girders; 11 the longitudinal arms of the cross shaped members in the top of the longitudinal center member; 12 the lateral arms of such crosses; 13 the transverse crowns which continue the cross arms to the car sides, and 14 the dumping doors which are hinged by floor beams 15 to the center member and extend outwardly to the car sides.

The longitudinal center member comprises, as shown, a pair of channel beams 20 (arranged with their webs vertical, and their flanges outward) a bottom plate 21 riveted to the lower flanges of the channel beams, a pair of vertical plates 22 extending parallel with the channels and above them and nearer together (these plates 22 being connected together at their upper ends by a curved crown) and suitable bridges, to be hereinafter described, supporting the vertical plates from the channels 20. The curved crown connecting the plates 22 is composed of the longitudinal arms 11 of the crosses and suitable filling blocks 25 between the longitudinal arms of successive crosses. These crosses are shown in Fig. 6, and the filling blocks are shaped similarly to the longitudinal arms of the cross. The longitudinal arms and the filling blocks each have a curved upper surface and depending vertical flanges 26 to which the plates 22 are riveted.

The floor beams of the dumping doors pass through openings 30 in the plates 22 and are pivoted by hinge pintles 31 at the center of the car to suitable supporting members, which may be vertical plates flanged and riveted to the plates 22, as shown at 32 in Figs. 3, and 5, or they may be webs depending from the crowns of the cross 11, or filling blocks 25, as shown at 34 in Fig. 7. The dumping doors carry shield plates 40 near their inner edges, and the hinge pintle being located at the center of curvature of the crowns 11 and 25, this shield plate makes close connection with such crowns, thus providing substantially a level bottom when the doors are closed, and making a slope tangent to the curve of the crown when the doors are dropped, thus greatly facilitating the discharge of the load, and preventing lodgment of material, as illustrated in the right hand half of Fig. 3.

I have stated that the plates 22 are supported by bridges secured to the channel. beams 20. The structure of these bridges varies with the strains to which the various parts of the center member are subjected, the connections being such as to form posts or struts at points where compression would take place and ties at tension points, so that the whole structure makes a truss, parts of the plates 22 and parts of the channels 20 acting as struts, ties and counters. By this means the structure may be very materially lightened without interfering with its strength or stiflness.

Fig. 2 shows the truss arrangement, the space between adjacent cross beams being shown as divided into three panels. Accordingly at points beneath the junction of the longitudinal and cross beams, and at two intermediate points the structure should have the character of a strut. At these points I provide bridges consisting of angle bars 50 having a horizontal portion extending across and riveted to the top flanges of the channels 20, as shown at 51; while the vertical portions of these angle bars are bent inward near their ends to lie along the inner face of the webs of the channels, being there riveted, as indicated at 52. Suitable angle pieces 53 lie against the outer face of the plates 22 and the upper surface of the bridge 50 and are riveted to such parts. This makes a very secure post. The downward strains act in shear on the horizontal rivets, this downward strain being also provided for by the extension of the bridge across the top of the channels 20, as explained.

At. points midway of the bridges 50, the structure should have the character of a tie or counter, as the strain at these points is tension. The plates 22 and the webs of the channels 20 make good tension members, and to prevent. these members pulling apart under such strain, I arrange the bridges at these points to act as ties. In this case, the bridge 60 comprises a channel with its web horizontal and its flanges facing downwardly, this channel lying between the two channel beams 20. The web of this channel bridge near its ends is turned downwardly and abuts the inner face of the channel beams, being there riveted by horizontal rivets, as indicated at 61.

62 designates vertical angle bars riveted to the plates 22 and to the webs of the channel bridge 60, the outer faces of which these angle bars engage. The outer flanges of these angles are also bent parallel with the channel beams 20 and riveted to their webs as shown at 65. In this instance, the rivets connecting the angle bars 62 with the plates 22, the channel bridge and the beams 20, and the rivets connecting the channel bridge with the beams 20, are all in shear for the tension strain coming at this point.

Downward bending of the longitudinal member would tend to cause the upper portion to shift lengthwise on the lower portion. This is eflectively resisted by the various rivets in shear of both the strut bridges and the tie bridges.

The plates 22 and the webs of the channels 20 together with my bridges 60 act as ties or counters for my center member truss. The truss action is indicated by the broken lines designated Strut Tie or Counter in Fig. 2.

The openings 30 in the plates 22, through which the floor beams project and swing, are so arranged as not to interfere with the line of direction of the ties or counters. Moreover, any weakening of the plate 22 by such opening is compensated for by the bracing which comes from riveting the cross plates 32 thereto, and by the flange of the corresponding angle bars 62. This is illustrated in Fig. 2.

It will be seen that my trussed center member provides for the various strains of compression, tension and bending to which such member may be subjected, and, as stated, enables this member to be made very light and at the same time very etticient in stiffness and strength. The particular shape of the member is also etticient in pro viding the central crowned floor member with which the dumping doors cooperate. To enable the hinge pintle of these doors to be conveniently placed or removed, I make horizontal elongations in the floor beam openings, as shown at 33 in Fig. 2. This elongation coming between the ties or counters as well as between the struts of the truss, does not materially weaken the plate, in its action as a strut, tie or counter.

In my car the longitudinal center member is designed to support the load which is above it and half of the load on the doors of each side thereof, while each car side is designed to support the load on half of the doors held thereby. The cross members between the sides and the center member are therefore simply beams to support whatever material may be carried by them, and to act as lateral bracing for the car floor frame. These beams consist of the transverse arms 12 of the crosses, the shedding crowns 13 and the underlying channel 70. This channel lies with its web horizontal and extends from the car side well toward the center, the web being riveted through the transverse arm 12 of the cross. The shedding crown 13 rests at its inner end on a reduced extension 71 of the arm 12 and its outer end on a block 72, the crown abutting against the tie member 73 which makes a lower chord for the girder side.

To provide end guards for the doors and also to securely heel the vertical posts 75 of the plate girder, I arrange these posts, which are preferably angle bars, in pairs with their projecting flanges adjacent and located slightly outside of the plane of the flanges of the channel 70. I extend these posts below the car side, and between the posts and the channel flanges, I place vertical plates 77 which constitute the end guards. These plates are riveted to the channel flanges, as shown at 78, and to the side posts 75, one of the rivets, as 79, passing through a side post, the plate and flange of the channel. I mount a suitable block 80 on the upper face of the projecting end of the channel 70 and between the vertical posts, this block being riveted. to the posts, the channel and car side, as shown in Fig. 4. The end guards may be stiffened by suitable reinforcing members riveted thereto, as the angle bars 81. This arrangement of parts not only operates to provide a very stiff end guard, but also securely heels the lower end of the vertical posts 75, making them effective cantalivers to resist outward bulging.
